5. Loosen the wire ropes on the counterweight end
of the machine. Remove the jam nut, then use
the flat on the end of wire rope anchor to hold it
while backing off the main nut. Leave the main
nut on the anchor about one full nut thread.

6. When all wire ropes are slackened, the disc
springs (washers) and spacers can be removed
from each wire rope anchor. Remove the
washers and spacers, then put the hex nut back
on one full nut thread to temporarily hold the
wire rope in place.
7. Once the wire ropes are slackened, remove the
boom flange pins and fasteners.
NOTE
The flange pins may not line up in the holes
exactly, but can be moved into place using a pry
bar once the cables are slackened.
8. Use two ¼-20 UNC bolts to help as a puller
when removing the flange pins. Threaded holes
are located in the flange pin collar. The bolts
should be full thread with no shoulder, and at
least 2 in. (50 mm) long.
